Introduction
Wind power is a process when kinetic energy is turned to electrical energy. For the wind turbine takes in the wind energy and then convert it into electrical energy. Wind power is well distributed and well known but due to the inventions of better energy producers they are now less widespread.
How does it work?
Wind power works when a turbine on a wind mill spins an internal generator, producing electrical energy. The energy source of wind farms are flowing air masses flow through an area of windmils. Each wid turbine has a total of 2-7 blades or pallets to take the energy of the force of wind. The energy from the flowing air masses causes the windmills to spin, turning the energy of the wind into kinetic energy. The generator makes use out of the kinetic energy, turing it into electrical energy. Even though one wind tubine can power 600 house holds an hour, it is quite uneffecient using only 40% of it efficiency. k How widespread is it?
Although over 86 countries from around the world use wind power the energy wind power creates is still very low and only countries with large surface area and windy areas are able to provide it. China is now the world's largest country that uses wind energy and in countries such as Africa Morocco,Egypt and SouthAfrica use this method. Through the countries wind power serve as small baches and in small wind farms creating fairly enough every for 600 households an hour. The top 10 wind power producing countries are China, India, South korea, Philippines, Argentina, Mexico, Egypt, Morocco, and South Africa are the major countries that produce wind power. The rate of the use of wind power is growing, 25% per year. How efficient is this?
Wind power is is not as effecient as many other methods of producing electricity. Methods such as Hydroelectric Powers, Nuclear Power, and Coal Powerare far more effecient producing more than their effciency but, wind turbines are expected to operate at 50%-60% efficiency although they onlyproduce at a 10% efficiency rate.
What are the benefits and drawbacks of this method of producing energy?
Benefits
ecofriendly to the air
simple structures does not pollute gas or smoke
one of the most ecofriendly energy producers wind is always there to power it
cheap and easy/simple to make
easy everyone can generate wind power
does not pollute gas
Drawbacks
not enough energy for cities
takes up a lot of surface area
need a windy direction
windfarms produce very little energy
people haveduring storms
some internal generators located inside the turbine may
cause smoke and sparks in the process
creates noise
cause impact on land forms
refered as non reliable power source
Enviromental issues
takes a lot of surface area
birds might caught up against wind blades
bad quality ones produce some smoke
a lot of surface area needed destroying forest
creates minor problems to the environment
ruin the landscapes of windy areas
birds and bats may occasionally get caught in turbines
What role will wind power serve in the future?
Since Wind power does not produce enough of electricity for cities they are mostly used in rural areas such as towns and small cities. Their appearance due to the space taking up the surface area wind turbines are less widespread. Even though current wind turbines are working at 40% of their efficiency, they are expected to work at 50%-60% efficiency. Although over 86 countries use wind power their numbers and the output of energy from wind turbines are very less unlike Hydroelectric Dams and Nuclear Power Plants. For wind power is less widespread. During the increase of human population for the desire of more electricity other energy sources would be used more often. Because of the going on population wind power would be less widespread. It is an eco friendly product but, a energy producer which is less efficient. Wind turbines need to be placed in a specific direction in the direction where wind blows the most and because of that and the surface area that it takes up small countries such as singapore can't afford to use them. In the future this product would be less widespread through the world as it is already now only 1% of the world's energy comes form wind energy. But now, as in today wind power is growing at 25% a year although other compatible energy sources are growing too more than the percentage of wind power.
